Fine over landline; but inconsistent on cellphones. :-P Before the CBC went digital, they had dedicated landlines to the NRC time signal lab.

- lbourdages 3y agoI just tested it against https://time.is https://time.is on my cell phone (using wifi calling because network strength is abysmal where I live). I don't have a precise measurement but it was imperceptibly close, within 100ms probably. Certainly close enough to set a clock for non critical purposes.
